VALVE-TOOL FOR REMOVING- THE VALVES FROM AUTOMOBILES.

Specification of Letters Patent.

Patented Mar. 28, 1916.

Application filed April 29, 1914. Serial N 0. 835,174.

To all whom it may concern:

Be it known that I, FRANK H. PIERCE, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Valve-Tools for Removing the Valves from Automobiles, of which the following is a specification.

My invention relates especially to a device for compressing the valve spring on an automobile so that the collar, pin, key or other form of retaining device may be easily removed.

To attain the desired end my invention consists of a combination of arms, sliding block, threaded levers, all of which will be hereinafter first fully described and then pointed out in the claim.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown a ferred form of embodiment of the invention,

Figure 1 is a side elevation illustrating a device embodying my invention, and Fig. 2 is a top plan view of the same.

The tool consists of the two arms 1 and 2. The lower arm 1 is stationary and has one end bent up at a right angle, to the top of which is hinged the upper or movable arm 2. The straight end of the stationary arm or base is cut out in a U shape so that it will fit around the valve lift. The loose end of the movable arm 2 may be straight or curved down, as the height of the lift requires.

The free end of the movable arm 2 is also cut out in a U shape the edges being recessed to receive the valve spring cup, or if the cup is large three pins are placed at the points and center of the U. The stationary arm 1 carries a sliding block 3 having in it a threaded hole. The sliding block 3 is actuated by a threaded shaft 4 extending through the bent up end of the stationary arm 1 and revolved by a wing handle 5.

shaft, wing handle, and.

merely pro-- Shaft 4 is free to rotate, but is fixed against longitudinal movement by means of a collar 7, and the threaded end of the shaft 4 en'- gages in the threaded hole of block 3. To the sides of the sliding block 3 are pivoted two levers 6 which are set on an upward slant toward the hinged end of the arms and are pivotally engaged at their upper ends to the movable arm approximately near its center, as indicated at 8.

In action the U shaped end of arm 1 is slipped around the valve lift and the threaded shaft 4: is revolved by the wing handle 5 which causes the shaft to screw into the sliding block 3 drawing it toward the hinged end of the arms. The lower ends of the levers 6 are thus drawn back by the block 3 and in turn force the movable arm 2 up, compressing the valve spring and holding it firmly so that the retaining device be it collar, pin or kev may be easily removed and the valve lifted out. To replace the valve reverse the operation.

WVhat I claim is:

In a device of the kind described, a base member, having an upturned end, amovable member pivoted to said upturned'end,'a

shaft mounted in said upturned end for rotation but fixed against longitudinal movement, said shaft having one end threaded and having its other end provided with a fixed finger-piece, a block provided with a threaded aperture to engage the threaded end of said shaft, and slidable along said base member, and pivoted connections between said block and said movable member, whereby when said ing block is caused to move, thereby to cause pivotal movement of said movable member.
